The following is a draft.

It is at best incomplete and at worst completely broken. In any case, it is not an "official" Xiph spec/codec, so use with care.

What is it

OggRGB is an uncompressed RGB (Red-Green-Blue) video codec for Ogg. It's a simple way to transfer raw, uncompressed RGB video within an Ogg container.

Why is it

The purpose of OggRGB is as a raw video interchange format within OggStream and other media frameworks. The format design is to be simple, complete, and efficient enough to be reasonably used to export decoded video to a media player for display.

Due to the size of uncompressed video, a compressed lossless video codec should be used for storage, such as would be prefered for video recording, editing, or archiving.

Format

Packets are processed as per the value of their first byte. Packets of unknown ID should be silently ignored, providing a convient way to add future expandability which does not break the data format. Additional data in packet 0 (the header packet) must also be silently ignored.
